A metal roof can rust, but the likelihood and rate of rusting depend on the type of metal used and the quality of the coating or treatment applied. Aluminium, for example, naturally resists corrosion due to its protective oxide layer. Selain itu, high-quality aluminum roofings are often processed with special finishes like powder coating or PVDF that further enhance their resistance to rust and other forms of corrosion. Namun, if the protective coating is damaged or compromised, the metal can be exposed to the elements, leading to rust over time. Regular maintenance and prompt repair of any damage can significantly extend the life of a metal roof and prevent rusting issues.
